Hi Engineers and Scientists,
I have made an attempt on a dimensional analysis question.
Consider the meniscus formed by a liquid of density rho and surface tension gamma within a capillary of radius r. Perform the dimensional analysis to determine the key dimensionless groups in this system. I did dimensional analysis on these 3 terms but it didn't give a dimensionless group. I tried adding gravity and came up with the characteristic length of the meniscus but this has a unit of length.
L = (gamma/rho*g)^0.5
I am hoping someone can tell me or give me some hints to help me identify the key dimensionless groups of this system.
Thanks.
